JOHN MGCLOSKEY, OF NEW YORK, N. Y.

IMPROVEMENT IN STEAM-PUMPS.

Specification forming part of Letters' Patent No. 89,158, dated April 20, 1869.

To all whom. 'it may concer/n:

Be it known that I, J oHN McULosxEY, of the city, county, and State of New York, have invented a new and Improved Steam-Pump; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

This invention relates to improvements in steam-pumps, designed more especially for employment in buildings, in connection with ranges for elevating water where it is not attainable from reservoirs, but is applicable for general use as a steam-pump.

It consists in the adaptation of 011e cylinder and two pistons to both the steam and water engine, and in the valve mechanism.

'The drawing represents a sectional elevation of my improved steam-pump.

A represents the cylinder, provided with a,

central partition, B, and a system of receiving and discharging water-valves, and their proper connections at each end. C and 0' represent pistons, arranged, respectively, on each side of the partition B, and connected to a hollow piston-rod, D, common to both, extending through stuffing-boxes at each end of the cylinder, having long tubular extensions E E. 'lhe said piston is closed at each end, and provided with openings F F for exhausting the steam. Gr represents the slidevalve, having tappets or arms a a projecting through the ports, one en each side of the partition B, by which it is moved, to open and close the ports, by the action of the pistons on the said tappets.

In the drawing the piston C is represented as being forced outward against the water, while the piston O' is moving inward, drawing water from the suction-pipe H, and at the point of striking the tappet a of the valve, whereby the latter will be moved to cut oi the supply behind the piston O, and open the port to admit the steam to act on the piston C'. At the end ofthe outward throw of the piston G the orifice F inthat end of the piston-rod will pass beyond the end of the tubular extension E', and allow the steam to escape'. A corresponding action takes place wilh reference to the other piston, C.

This arrangement provides an elevating apparatus of very cheap construction, which requires little or no attention, and aifords a reliable pump for household and other purposes,

\to which the steam may be supplied from the cylinder, and suitable pistons attached to the rod D, extending through them and exhausting, as herein described 5 or, if it be required for a motor for driving other machinery, the water-pipes and valves may be dispensed with, and the proper connection of the mechanism to be operated made to the ends ot' the piston; or, when having the said pipes and valves, it may be so used by stopping the iiow of the water.

I claim as new and desire to secure by Letters Patent- 1. The cylinder A, provided with the partition B and the pistons C C', connected by the hollow piston-rod D, all arrangedl as herein shown and described.

2. The hollow piston D, having orices F and F', as described, the tubular extensions E and E', in combination with the pistons C C and cylinder A, substantially as and for the purpose specified.

3. The arrangement of the cylinder A, having the partition B and the pistons C G', with the pump-valve mechanism, arranged substantially as specified.

et. The construction and arrangement of the valve G and projections a with reference to the pistons C C and partition B, substantially as herein set forth.

The above specification of my invention signed by me this 11th day of December, 1868.

JOHN MOCLOSKEY.
